4.0

(9)

Bottom Line

Choose if you want premium cordless suction and a flexible 3-in-1 design with twin-battery option; Skip if you need a lighter, more nimble stick or a bigger, easier-to-empty bin at this price.

Best for

Homes that want top-tier cordless pickup (especially fine dust) plus flexible 3-in-1 configurations and don’t mind paying for premium build and filtration.

Not for

Large homes or anyone who hates frequent bin emptying, fiddly conversions, or brush maintenance; also budget-focused shoppers who can get similar cleaning results for less.

Verdict

The Triflex HX2 Pro consistently tests as a powerhouse on fine dust and everyday debris, and reviewers praise its premium build, sealed HEPA-style filtration, and flexible 3-in-1 configurations that can stand on their own. The tradeoff is practicality: the 0.5L bin fills fast and can be messy or fiddly to empty, roller swaps and mode changes can feel clunky, and hair may tangle on the brush depending on the floorhead and use. Runtime is strong in low/eco modes with the spare battery, but Max/boost drains quickly, so large homes may require pauses to swap batteries and empty the bin. At its premium price, several reviewers suggest better value alternatives if you prioritize agility and convenience.

Suction & Airflow 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.5

Accessories & Tools 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.5

Cyclone performance 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.5

On medium-pile carpet, tests often report strong pickup (including pet hair) but sometimes requiring multiple passes for a truly clean finish.
Onboard tool storage 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.4

Onboard/wall storage for small tools is viewed as convenient, though some wish every tool had a dedicated onboard slot.
Floorhead design 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.4

The floorhead earns praise for wide coverage, strong sealing/suction-to-floor feel and surface versatility; downsides include limited swivel/flex in some designs and a tendency to snowplow larger debris on hard floors in certain tests.
Convertible handheld design 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.4

Handheld conversion is a core strength and works well for stairs, cars and spot jobs, though it can feel heavy for extended above-shoulder cleaning.

Cordless convenience 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.3

Cordless freedom is a major benefit, especially paired with swappable batteries; frequent bin emptying can reduce the sense of convenience for some owners.
AI, Smart & App / Automation 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.3

Automatic floor-type sensing/brush behavior is a notable feature, adjusting suction or brush action when moving between hard floors and carpet; responsiveness is sometimes slower than top rivals but generally effective.
Carpet — High-Pile Pickup 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.2

High-pile/thick carpet results are generally good but can become hard to push at higher suction, making mid modes more practical.
Battery & Charging 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.1

Battery system is a strong point on Pro bundles thanks to a spare pack and multiple charging options; charge times around ~4 hours and occasional quirks mean you’ll want a charging routine, especially if you use higher power often.

Against competitors, reviewers agree it performs very well on cleaning tests, but several note that premium Dysons can outperform it while costing less in some markets.
Upholstery / Above-Floor Pickup 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.8

Above-floor cleaning with upholstery/crevice tools is generally effective, but the unit’s weight can make extended high-reach cleaning tiring, and some embedded sofa debris (like feathers) may still resist pickup.
Dried-On Stain Removal 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.8

Handling feedback is mixed: some find it easy to manoeuvre (especially in comfort/low-mounted mode), while others call it clumsy, less flexible when turning, or hard to push/pull on certain settings.
Assembly and Setup 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.8

Initial setup/assembly is usually straightforward, but some reviewers report stiff parts and multiple steps when reconfiguring between modes.
Runtime (Measured, Default) 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.7

Measured/realistic runtime varies widely by mode and attachment: low/min settings can reach roughly an hour per battery in some setups, while typical eco use is often closer to ~20–30 minutes.
Under-Furniture Pickup 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.6

Under-furniture access is one reason to reconfigure the power unit; some reviewers still find the vacuum heavy or the benefit modest versus conventional stick designs.
Hard Floor — Large Debris Intake 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.6

Large debris on hard floors is inconsistent: some testers report easy pickup of rice/cereal, while others see snowplowing or flinging that requires technique changes or switching to handheld/nozzle mode.
Weight 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.6

Weight impressions vary: some find it heavy compared to most cordless sticks, while others find it manageable—especially with the power unit mounted low to reduce wrist strain.

Cons

Maintenance requirements 3.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.4

Maintenance is a mix of positives and negatives: washable parts and filter-cleaning features help, but bin emptying, filter brushing and hair removal can be time-consuming for some owners.
Controls & UI 3.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.3

Controls are simple but polarizing: the slider and basic indicators are easy to understand, yet some find the interface less refined or a bit cumbersome to adjust precisely.
Runtime (Measured, Boost/Turbo) 3.1 ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.1

Boost/Max runtime is consistently short (often around ~8–15 minutes per battery), so it’s best treated as a spot-cleaning mode rather than a whole-home default.
Tool-change simplicity 3.1 ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.1

Swapping rollers and converting configurations is often described as slower or more fiddly than rivals; users who rarely change modes will mind this less.
Price & Value 3.0 ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.0

Value is a common pain point: performance and build are praised, but many reviewers feel the high price is hard to justify versus strong competitors.
Hair‑Wrap / Tangle Resistance 3.0 ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.0

Hair-wrap resistance is mixed: some reviewers report little to no tangling, while others (including lab tests) note hair wrapping and a lack of robust anti-tangle tech compared with Shark/Dyson.
Bin & Bag 3.0 ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.0

The 0.5L bin is widely considered small for the class; it can fill quickly during whole-home cleans, though a few reviewers find it adequate for average runs.
Emptying & Mess Control 2.7 ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 2.7

Emptying can be fiddly and sometimes dusty; several reviews recommend emptying outdoors, while others note it can be controlled with practice but remains a frequent annoyance due to bin size.

FAQ

Does it really clean well on both hard floors and carpet?

Most reviews report excellent pickup across surfaces, especially fine dust. Large debris on hard floors can be inconsistent in some tests, sometimes requiring a slower approach or switching to handheld/nozzle mode.

How long does the battery last in real use?

Runtime depends heavily on mode and the powered floorhead. Low/min can approach about an hour per battery in some setups, while typical eco use is often closer to 20–30 minutes, and Max/boost commonly drops to around 8–15 minutes per battery.

Is the dustbin too small?

Many reviewers say the 0.5L bin fills quickly during whole-home cleans and becomes the main annoyance. A few find it adequate for average sessions, but frequent emptying is common.

Does hair wrap around the brush?

Feedback is mixed. Some reviewers report minimal tangling, while others note hair wrapping and the need to cut it free, especially compared with vacuums that have stronger anti-tangle designs.

Is it easy to switch modes and rollers?

The 3-in-1 design is flexible, but multiple reviews call mode changes and roller swaps more fiddly or slower than rivals. If you mostly stay in one configuration, it’s less of an issue.

Is it worth the price?

Reviewers generally agree the cleaning power and build are premium, but many question the value because of the small bin and usability quirks. If convenience and price-to-performance matter most, alternatives may make more sense.
